Abstract Vibration analysis of rods that are subjected to rotation is presented. It is shown that flexural-flexural, longitudinal-flexural and torsional-flexural wave coupling occur due to the Coriolis Effect. First, we carried out our analysis for thin rods where the wavelength is much larger than the radius. It is shown that the wavenumbers change due to the Coriolis Effect. Then, we characterize the 3-D wave propagation in rotating rods by using the Finite Element Method (FEM) in order to determine the corresponding wavenumber shifts for each type of wave. We show that for different drive frequency (ω0) and rotation rate (Ω), wave couplings exhibit different characteristics. For flexural-flexural wave coupling, the wavenumber increases for the primary flexural wave whereas the wave number decreases for the coupled flexural wave where Ω

弹性波在棒中传播的科里奥利效应

摘要 介绍了旋转杆的振动分析。结果表明，由于科里奥利效应，发生弯曲-弯曲、纵向-弯曲和扭转-弯曲波耦合。首先，我们对波长远大于半径的细棒进行了分析。结果表明，波数因科里奥利效应而发生变化。然后，我们通过使用有限元方法 (FEM) 来表征旋转杆中的 3-D 波传播，以确定每种波的相应波数偏移。我们表明，对于不同的驱动频率 (ω0) 和旋转速率 (Ω)，波耦合表现出不同的特性。对于弯曲-弯曲波耦合，主弯曲波的波数增加，而耦合弯曲波的波数减少，其中 Ω
